We all have a unique odor that emanates from our bodies, and it’s perfectly natural. Sweat is our body’s way of cooling down when we’re hot, and it’s produced by millions of glands all over our skin. While sweat is mostly water, it contains traces of salt, minerals, and waste products. Sweat itself doesn’t have any smell, but when it interacts with bacteria on our skin, it can produce an unpleasant odor. However, sometimes sweat can cause discoloration, which can be embarrassing and confusing. In this article, we’ll explore why your armpits might turn yellow and what you can do about it.

Why are my Armpits Yellow?

Why do armpits turn yellow?

There are several reasons why your armpits might turn yellow. Here are a few of the most common causes:

Sweat stains

Sweat stains are the most common reason for yellow underarm stains on clothes. Sweat stains are caused by the aluminum in antiperspirant reacting with the salts in sweat. The reaction produces a yellowish stain that can be difficult to remove from clothing. If you wear light-colored clothing, the stains can be even more noticeable.

Deodorant stains

Deodorants can also cause yellow armpit stains. Deodorants work by killing the bacteria that produce odor on your skin. However, the chemicals in some deodorants can react with the salts in your sweat, causing a yellowish stain on your clothes.

Dead skin cells

Dead skin cells can also cause yellow armpit stains. When we sweat, our skin sheds dead skin cells. These cells can mix with the sweat and create a yellowish stain on our clothing. This type of stain is more common in people who don’t exfoliate regularly.

Certain medical conditions

Some medical conditions can cause yellow armpit stains. For example, people with hyperhidrosis, a condition that causes excessive sweating, may experience yellow stains on their clothing. Other medical conditions that can cause yellow stains include liver disease, kidney disease, and diabetes.

What can you do about yellow armpit stains?

Now that we’ve explored some of the most common causes of yellow armpit stains, let’s look at some ways to get rid of them:

Use a stain remover

One of the easiest ways to get rid of yellow armpit stains is to use a stain remover. There are several products on the market that are specifically designed to remove sweat stains. Look for a stain remover that contains enzymes, which break down the proteins in sweat.

Switch to a natural deodorant

If you’re experiencing yellow armpit stains because of your deodorant, consider switching to a natural deodorant. Natural deodorants are made with ingredients like baking soda, coconut oil, and essential oils, which are less likely to react with the salts in your sweat.

Exfoliate regularly

If you’re experiencing yellow armpit stains because of dead skin cells, consider exfoliating regularly. Exfoliating removes dead skin cells and promotes healthy skin regeneration. You can use a gentle exfoliating scrub or a loofah to exfoliate your underarms.

See a doctor

If you’re experiencing yellow armpit stains because of a medical condition, it’s important to see a doctor. Your doctor can diagnose and treat the underlying condition, which may help reduce or eliminate the yellow stains.

Practice good hygiene

Practicing good hygiene is an essential way to prevent yellow armpit stains. Make sure to shower daily and use an antibacterial soap to clean your underarms thoroughly. This will help to reduce the number of bacteria on your skin and minimize odor.

Wear breathable clothing

Wearing breathable clothing is also crucial in preventing yellow armpit stains. Clothing made from synthetic fabrics can trap sweat and bacteria, leading to more yellow stains. Instead, opt for clothing made from natural fabrics like cotton or linen, which allow for better airflow and ventilation.

Avoid excessive sweating

Avoiding excessive sweating is another way to prevent yellow armpit stains. If you’re prone to excessive sweating, try wearing sweat-wicking clothing or applying an antiperspirant to your underarms. Additionally, you can try to avoid activities or environments that make you sweat excessively.

Use lemon juice

Lemon juice is a natural bleaching agent that can help to remove yellow armpit stains. Simply cut a lemon in half and rub it onto the affected area. Let it sit for 30 minutes before washing it off with warm water. Repeat this process a few times a week to see results.

Try baking soda

Baking soda is another natural remedy that can help to remove yellow armpit stains. Mix equal parts of baking soda and water to create a paste. Apply the paste to the affected area and let it sit for 30 minutes before washing it off with warm water. Repeat this process once a week to see results.

Consider professional treatment

If you’ve tried all of the above remedies and still can’t get rid of your yellow armpit stains, consider professional treatment. There are several treatments available, including laser treatment, that can help to reduce or eliminate yellow armpit stains.


In conclusion, yellow armpit stains can be embarrassing, but they’re also perfectly normal. By understanding the causes of yellow armpit stains and taking steps to prevent them, you can feel more confident and comfortable in your own skin. Remember to practice good hygiene, wear breathable clothing, and consider natural remedies and professional treatment if needed.
